Product Overview
The Zirconiated Tungsten Electrode (Alum White, 1.0mm) is a premium-grade non-consumable electrode engineered for precision AC TIG (GTAW) welding. Identified by its distinctive white color band, this electrode contains approximately 0.15%–0.40% zirconium oxide (ZrO2) alloyed with pure tungsten, delivering an optimal balance of arc stability, contamination resistance, and current-carrying capacity — making it the go-to choice for welders working with aluminum, magnesium, and other non-ferrous metals.
Key Features
- Zirconium Oxide Alloy: Combines the arc stability of pure tungsten with improved current-carrying capacity and resistance to contamination
- Excellent Balled Tip Retention: Maintains a clean, rounded tip shape under AC welding conditions, ideal for aluminum and magnesium applications
- High Contamination Resistance: Less prone to tungsten inclusion in the weld pool compared to pure tungsten electrodes
- Superior Arc Starting: Provides smooth, reliable arc initiation and excellent arc stability throughout the weld
- Precision Diameter: 1.0mm diameter suited for thin-gauge and precision welding applications
- Color-Coded for Easy Identification: White tip/band per AWS A5.12 classification (EWZr) standards

Why Choose Zirconiated Tungsten?
Zirconiated tungsten electrodes are often considered the best all-around choice for pure AC welding, offering many of the arc-starting benefits of pure tungsten combined with better durability and lower risk of tungsten contamination in the weld — a critical advantage for industries like aerospace, automotive, and structural fabrication where weld purity is essential.
